The heat dissipation channel 701 penetrates through the GPU70 along a first direction, and the front air inlet 702 of the heat dissipation channel 701 is in butt joint communication with the second air guiding opening 712. The rear air inlets 703 of the heat dissipation channel 701 may face the corresponding air outlets 15 at intervals, or may be in butt joint communication with the corresponding air outlets 15 by the way that the GPU70 is in butt joint with the rear panel 112. In this embodiment, the rear end of the GPU70 is butted against the rear panel 112, and the rear air inlet 703 of the heat dissipation channel 701 is butted and communicated with the first air outlet. Thus, the system fan 67 can transmit cool air to the GPU70 through the air duct 71, and discharge heat generated by the GPU70 out of the casing 1 through the first exhaust hole 1521.

A bracket 72 is fixedly arranged on the surface of the air guide pipe 71. The bracket 72 is used for fixing the air guide duct 71 in the casing 1. The bracket 72 includes: an attachment portion 721, and a connection portion 722. One end of the connecting part 722 is fixedly connected with the guide tube, and the other end of the connecting part 722 is connected with the mounting part 721; the mounting portion 721 is formed with a mounting hole 723. The mounting portion 721 is used to fix the air duct 71 in the casing 1 by the engagement of the mounting hole 723 and the screw.

In the present embodiment, the brackets 72 are disposed at the front and rear ends of the air guide duct 71, but not limited thereto. The mounting part 721 of the bracket 72 at the rear end is located on the right side of the air duct 71, and the bracket 72 at the rear end is detachably and fixedly connected to the circuit board 66 by a screw. The mounting part 721 of the bracket 72 at the front end is located right below the air duct 71, and the bracket 72 at the front end is detachably and fixedly connected to the bottom plate by a screw. By disposing the bracket 72 at the front end directly below the air guide duct 71, the area of the air guide duct 71 that needs to be occupied in the horizontal direction when installed in the cabinet 1 can be reduced.

Further, an avoiding opening 713 is formed in the front end of the air guide pipe 71, the avoiding opening 713 penetrates through the air guide pipe 71 in the up-down direction, and the avoiding opening 713 faces the mounting hole 723, that is, the avoiding opening 713 is vertically overlapped with the mounting hole 723 located at the front end of the air guide pipe 71. The installation part 721 can be fixed to the casing 1 with a screw by opening the escape opening 713 with a screwdriver.

With reference to fig. 1 and 7, when the hard disk fan 68, the system fan 67, the cooling fan and the power supply fan work simultaneously, the main flowing direction of the wind in the casing 1 is as follows:

first, the external cold air enters the air intake region 131 from the left and right sides of the front end of the cabinet 1 through the first and second air intake holes 141 and 142. Then, a part of the cold air on the left side of the hard disk assembly 5 passes through the hard disk assembly 5 from left to right under the action of the hard disk fan 68 to cool the hard disk assembly 5, and the air passing through the hard disk assembly 5 and the cold air entering through the first air inlet 141 enter the heat dissipation area 132 through the first through hole 211 under the action of the system fan 67; part of the air enters the GPU70 through the air guide pipe 71, ventilates and dissipates heat of the GPU70, and finally is exhausted out of the shell 1 through the first exhaust hole 1521; a part of the air passes through the insertion groove 65, ventilates and dissipates heat of the expansion card on the insertion groove 65, and finally is exhausted out of the casing 1 through the second exhaust hole 1522; in addition, a part of the air passes through the corresponding radiator 63 under the guidance of the radiator fan on the first heat source 61 so as to achieve the purpose of radiating the first heat source 61 by ventilating and radiating the radiator 63, the air passing through the radiator 63 on the first heat source 61 flows to the rear right of the second heat source 62 under the guidance of the first air deflector 31 so as to bypass the second heat source 62 and the radiator 63 on the second heat source 62, and finally is discharged out of the cabinet 1 through the third exhaust hole 1523 and the top exhaust hole 151. The other part of the cool air on the left side of the hard disk assembly 5 enters the heat dissipation area 132 through the second via hole 212, the cool air entering the heat dissipation area 132 through the second via hole 212 is divided into two parts under the action of the power supply fan and the heat dissipation fan on the second heat source 62 and under the action of the fifth air deflector 42, one part of the cool air flows to the power supply module 69 and is exhausted out of the enclosure 1 through the fourth exhaust hole 1524 after dissipating heat to the power supply module 69, the other part of the cool air flows to the corresponding heat sink 63 under the common limitation of the first air deflector 3 and the second air deflector 4 so as to achieve the purpose of dissipating heat to the second heat source 62 by ventilating and dissipating heat to the heat sink 63, and the air passing through the heat sink 63 on the second heat source 62 is finally exhausted out of the enclosure 1 through the third exhaust hole 1523 and the top exhaust hole 151.

The first air guide 3 and the second air guide 4 are arranged, so that the air inlet and outlet paths of the two groups of radiators 63 can be effectively separated, the air outlet end of the front group of radiators 63 bypasses the air inlet end of the rear group of radiators 63, and the influence of hot air exhausted from the front radiators 63 on the rear CPU is avoided. The air intake end of the rear radiator 63 is additionally supplied from other regions in the turning direction of the first air guide 3 and the second air guide 4, and is no longer in an interaction relationship with the front radiator 63 on the air passage. In addition, the air guide pipe 71 is arranged, so that a channel for independently ventilating and radiating the GPU70 is formed, the GPU70 can be ensured to radiate smoothly, the GPU70 can keep good working performance, the aging speed of the GPU70 is reduced, and the service life of the GPU70 is prolonged. In addition, the air inlet holes 14 are formed on the left side and the right side of the chassis, so that more devices and device interfaces can be mounted on the front panel 111. In addition, the partition plate 2 not only can support the system fan 67, but also can prevent the wind with heat in the heat dissipation area 132 from flowing back to the air inlet ends of the system fan 67 and the hard disk fan 68, so as to reduce the heat dissipation efficiency of the devices in the casing 1.

The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
